The Freedom Union (Polish: Unia Wolności, UW) was a liberal[6] democratic political party in Poland that was active from 1994 to 2005, when it rebranded and became the Democratic Party.

It represented European democratic and liberal tradition, i.e., it advocated free market economy and individual liberty, rejected extremism and fanaticism, favoured European integration (in the form of European Union membership), rapid privatisation of the enterprises still owned by the Polish state and decentralisation of the government.

In January 2001 some members of the FU (mostly from centre-right and KLD factions) decided to move to join the new Civic Platform (Platforma Obywatelska), which got 12.7% of the votes and 65 seats in the September 2001 general elections whilst the FU failed to cross the 5% threshold required to gain entry to the lower house of Parliament, receiving only 3.1%.

The initiative by the FU leadership to found the centre/social-liberal Democratic Party (Partia Demokratyczna – demokraci.pl) attracted a lot of attention.

Legally the centrist Democratic Party, founded 9 May 2005, is the successor of the FU.
